IMPORTANT: The auto-MDIX feature is always activated on the gateway. This feature automatically
detects the required cable connection type (straight or crossed), and configures the connection
appropriately, removing the need for crossover cables. In order for auto-MDIX to work correctly,
auto-negotiation (auto speed and auto duplex) must be enabled on both sides of the link. Note that
auto negotiation is always active on the gateway.
